Oxidative dehydrogenation of ethane with carbon dioxide over silica molecular sieves supported chromium oxides: Pore size effect

Zhibin Deng et al.

Summary: SBA-15 with varied pore size from 4 to 8 nm were synthesized and used to load CrOx active phase, leading to catalysts with well dispersed metal species. The pore size had profound effects on reducibility, surface composition and basicity, where Cr6+ species played a key role in activating C-H bonds of alkanes and basicity was important for activating C-O bonds of CO2. The best performance was achieved over the sample with a pore diameter of 7 nm in oxidative dehydrogenation of ethane in the presence of CO2.

Ethane Dehydrogenation on Single and Dual Centers of Ga-modified γ-Al2O3

Sai Praneet Batchu et al.

Summary: Density functional theory calculations and microkinetic analysis were used to investigate the efficacy of Ga-modified gamma-Al2O3 (110) surfaces for the catalytic dehydrogenation of ethane and the synergy between Ga and Al sites. It was found that doped Ga sites exhibited significantly higher catalytic activity compared to grafted Ga sites, and an increase in surface water interfered with the synergy between Al and Ga sites.

Strain in Silica-Supported Ga(III) Sites: Neither Too Much nor Too Little for Propane Dehydrogenation Catalytic Activity

C. S. Praveen et al.

Summary: The study evaluates the catalytic activity of Ga(III) sites on SiO2 towards propane dehydrogenation (PDH) reaction using first-principles calculations. The research demonstrates the importance of strain on the reactivity of these sites, highlighting the need for a balance in strain for an effective catalytic site for PDH. Overall, the work provides insights into the intrinsic activity of acidic Ga single sites on SiO2 towards the PDH reaction and suggests potential for designing better single-site catalysts.

Mechanism and Kinetics of Light Alkane Dehydrogenation and Cracking over Isolated Ga Species in Ga/H-MFI

Neelay M. Phadke et al.

Summary: The study investigated the mechanisms and kinetics of C2H6 and n-C4H10 dehydrogenation and cracking over isolated Ga species in Ga/H-MFI, comparing the results to those reported previously for C3H8 dehydrogenation and cracking. The findings suggest that C2H6 dehydrogenation is catalyzed by both [GaH](2+) and [GaH2](+) cations, while C4H10 dehydrogenation and cracking are exclusively catalyzed by [GaH](2+) cations. The reaction kinetics demonstrate a common mechanism occurring over [GaH](2+), similar to that reported for C3H8 dehydrogenation/cracking over Ga/H-MFI.

Sai Chen et al.

Summary: The review discusses recent advances in understanding the PDH process, including emerging technologies, catalyst development, and new chemistry for regulating catalyst structures and inhibiting catalyst deactivation. Analysis and discussion on active sites, reaction pathways, and deactivation mechanisms of PDH over metals and metal oxides, as well as their dependent factors, are provided to enable efficient catalyst design for minimizing reaction barriers and controlling selectivity towards propylene. Challenges and perspectives of PDH over heterogeneous catalysts are also proposed for further development.
